Can I order material for a commercial or contractor job?

Yes. Virginia Rock Supply supplies bulk aggregate for contractor and commercial work across Fairfax County, from driveway bases to drainage and site fill. Order by the ton or the yard and size each load to the phase you are building. Tell us the material, the quantity and the access when you place the order online.

When is the best time of year to order base material in Fairfax County?

Late spring through fall is easiest. Frozen or snow-covered ground in midwinter and saturated clay after thaws and long wet spells hold base and driveway work up. Frost depth is 24 inches here, so freeze-thaw heave is a real winter factor. Order when the ground is workable and can be compacted.

What is the difference between topsoil and fill dirt?

Fill dirt is bulk material for raising grade and building up a pad before the 21A goes down. Topsoil is screened and meant for growing, so it goes on last for lawns and beds over red clay or thin, sandy ground. Use fill to shape the site, then topsoil to plant it.

Start with 21A. It is the standard Virginia driveway base. Clay ground here needs a base that locks up, and 21A does.

Materials Delivered in Fairfax County

21A carries most of the work in this county. Order it for driveways, parking pads, and the base under sheds and patios. It goes down over fill dirt and stays put.

Around that base, the rest of the list covers drainage, bedding and finish work.

Pair it with Drain Rock for French drains and downspout runs, and use Top Soil or Fill Dirt when the grade needs building before the base goes down.

Ground Conditions Across Fairfax County

Watch a thin base fail first. A thin layer of 21A over clay ruts, pumps and spreads within a season. The fix is depth and compaction, not a different stone.

Most of this county sits on clay-rich soil weathered from Piedmont rock, with sandstone, siltstone and diabase ground in the Culpeper Basin. A Coastal Plain strip along and east of I-95 carries shrink-swell marine clay that swells when wet and shrinks when dry. That movement cracks slabs and shifts pads.

Clay takes in water slowly. Summer thunderstorms and the remnants of tropical systems run off fast, most of all where development has paved the ground. Sediment then washes off bare clay on building sites and slopes, and stream banks scour after heavy storms. Arm those spots with rip rap and give water a path out with #57 stone or drain rock.

Winter adds freeze-thaw heave. Frost depth is set by each locality, and it is 24 inches in Fairfax County. Midwinter frozen ground and saturated clay after thaws hold base and driveway work up, so plan around them.

Delivery Across Fairfax County

Order online. Choose tons or yards, then estimate quantity from length, width and depth. Bulk delivery drops the load where the truck can reach, so tell us about tight gates, low wires and soft ground up front.

We deliver to Centreville, Reston, McLean, Burke, Annandale, Oakton, Springfield, Herndon, Chantilly, Lorton, Merrifield, Vienna, Great Falls and Fairfax Station. A dump truck spreads as it tips, which saves wheelbarrow trips on a long drive.

Choosing the Right Material

Ground changes as you cross the county line, and the material should follow. Prince William County and Loudoun County sit in the same Northern Virginia Piedmont zone as Fairfax, so the ground is similar and the base choice usually is too. Expect the same clay, the same slow intake, and the same 21A base under drives and pads.

Arlington County shares that zone as well, but its lots are smaller and more of the ground is already paved. There, drainage and tight access matter more than bulk base, so #8 stone, screenings and drain rock often carry the job.

Across all four counties, match the material to the failure you are fixing. Rutting and soft spots call for deeper 21A. Standing water calls for washed stone. Bare slopes call for rip rap.
